# Stage 3, mathematics, Year A – Unit 07

This 2-week unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

Students are provided opportunities to:

• determine products and factors
• use partitioning and place value to multiply 2, 3 and 4-digit numbers by one-digit numbers
• represent and solve division problems with whole number remainders.
